A method for efficiently producing a cyanogen halide with suppressed side effects, and a method for producing a high-purity cyanate ester compound at a high yield includes contacting a halogen molecule with an aqueous solution containing hydrogen cyanide and/or a metal cyanide, so that the hydrogen cyanide and/or the metal cyanide is allowed to react with the halogen molecule in the reaction solution to obtain the cyanogen halide, wherein more than 1 mole of the hydrogen cyanide or the metal cyanide is used based on 1 mole of the halogen molecule, and when an amount of substance of an unreacted hydrogen cyanide or an unreacted metal cyanide is defined as mole (A) and an amount of substance of the generated cyanogen halide is defined as mole (B), the reaction is terminated in a state in which (A):(A)+(B) is between 0.00009:1 and 0.2:1.
一种用于高效生产抑制副作用的氰卤化物,以及以高收率生产高纯度氰酸酯化合物的方法包括将卤素分子与含有氢氰酸和/或金属氰化物的水溶液接触,使得氢氰酸和/或金属氰化物与卤素分子在反应溶液中发生反应以获得氰卤化物,其中基于1摩尔卤素分子使用超过1摩尔的氢氰酸或金属氰化物,当未反应的氢氰酸或未反应的金属氰化物的物质量定义为摩尔(A),生成的氰卤化物的物质量定义为摩尔(B),反应在(A):(A)+(B)介于0.00009:1和0.2:1之间的状态中终止。
